This Privacy Policy governs the PDF Sprint mobile application and all associated services operated by Dian Wu (together referred to as the “Application”). Dian Wu shall be named the “Service Provider” herein.
The Service Provider gathers information when you download and interact with the Application. Collected data may include:
Your device’s Internet Protocol (IP) address
Pages you access within the Application, access timestamps, and the amount of time spent on each page
Total usage duration of the Application
Your mobile operating system type
The Application and integrated third-party SDKs may deploy cookies, software development kits, tracking pixels and comparable technologies to enable core features, conduct analytics and deliver services. In jurisdictions where relevant legislation applies, the Service Provider will obtain your consent prior to deploying non-essential tracking tools.
You are entitled to submit requests to access, rectify or erase personal data held by the Service Provider. If data processing relies on your consent, you may also withdraw such consent at any time. To exercise these rights, reach out to the Service Provider via bradcliffav@gmail.com.
If you are a resident of California, you hold the rights to learn what personal data we collect, request deletion of your personal information, opt out of any sale or sharing of your personal data, and receive equal treatment without discrimination when exercising these privacy rights. Submit your CCPA/CPRA-related requests by emailing bradcliffav@gmail.com.
The Service Provider may utilise information you supply to transmit critical updates, mandatory service notices, and marketing communications where permitted under law.
To optimise your experience using the Application, the Service Provider may request certain personally identifiable information, including contact email bradcliffav@gmail.com. All requested information will be stored and utilised strictly in accordance with this Privacy Policy.
Only aggregated, anonymised data is periodically shared with external parties to support ongoing improvements to the Application and related services. The Service Provider may disclose your information to third parties in the ways outlined within this Privacy Policy.
The Service Provider and its third-party service partners may transfer personal data to territories outside your country of residence, including regions beyond the European Economic Area (EEA). When local laws mandate protective measures for cross-border data transfers, the Service Provider will implement suitable safeguards via one or more of the following mechanisms:
Standard Contractual Clauses (SCCs) endorsed by the European Commission
Adequacy decisions or other legally recognised data transfer frameworks
Your explicit consent, where applicable and legally permissible
Data protection regulations in foreign jurisdictions may differ from those applicable in your region. Where legally required, the Service Provider will enforce appropriate safeguards and secure all necessary consent for international data transfers.
Please be advised that the Application integrates third-party services which maintain their own independent privacy policies governing data handling. A link to the privacy policy of the third-party provider used within the Application is listed below:
The Service Provider may disclose user-provided and automatically collected information under the following circumstances:
When required by law, such as responding to subpoenas or comparable legal demands;
When acting in good faith to protect its legitimate rights, safeguard your safety or the safety of others, investigate fraudulent conduct, or respond to official government inquiries;
To trusted service providers acting on its behalf, who are prohibited from independently using the disclosed information and have committed to comply with the rules set out in this Privacy Policy.
You can halt ongoing information collection from your mobile device by uninstalling the Application. Uninstallation stops the Application from gathering new data from your device, but it does not automatically remove information already transmitted to the Service Provider or relevant third parties.
To submit a data deletion request, withdraw consent, or exercise any of your privacy rights, email the Service Provider at bradcliffav@gmail.com.
The Service Provider retains personal data only for periods necessary to fulfil defined purposes, following the retention rules below:
User Provided Data: Stored throughout your period of Application usage, plus an additional 12 months thereafter, unless a longer retention period is mandated by law.
Automatically Collected Data: Retained for a maximum of 24 months following collection, except when extended retention is needed for legal compliance.
Aggregated and Anonymised Data: Preserved indefinitely, as such data can no longer be linked to identify you.
Data required to satisfy legal obligations: Kept for the duration specified by applicable legislation.
You may submit a request to erase your personal data, subject to any statutory obligations forcing continued data storage. If you wish the Service Provider to delete user-provided data submitted via the Application, contact us at bradcliffav@gmail.com. Kindly note that certain user-provided data may be essential to maintain normal operation of the Application.
The Application is not designed for users under the age of 16, or the higher minimum age specified by applicable local law. The Service Provider does not intentionally collect data from minors or direct marketing of the Application toward children.
Where local regulations demand parental or guardian consent for minors to use online services, the Application may not be used without such authorisation. The Service Provider will not knowingly collect personally identifiable information from children under 16 in breach of relevant laws. If we discover personal data has been submitted by a minor, we will immediately remove such information from our servers. If you are a parent or legal guardian and become aware your child has shared personal information with the Service Provider, please contact us at bradcliffav@gmail.com so we can take appropriate action.
The Service Provider prioritises protecting the confidentiality of your personal information. We maintain physical, electronic and procedural security measures to safeguard all data we process and store.
In the event of a security breach impacting your personal data, the Service Provider will issue notifications in compliance with relevant legal requirements, including supplying details about the breach nature and remedial actions underway where required.
The Service Provider reserves the right to revise this Privacy Policy periodically. Material revisions will be communicated by publishing the updated version alongside a new effective date. If required by law, we will obtain your consent prior to implementing material changes.
Historical versions of this Privacy Policy will be preserved and can be accessed upon request by emailing bradcliffav@gmail.com.
This Privacy Policy takes effect on 2026-07-27.
Where data processing relies on consent, you grant consent by actively opting into the corresponding feature or action. You are free to withdraw consent at any time; withdrawal will not affect lawfully completed processing activities carried out prior to revocation. Processing activities based on other lawful grounds will continue in accordance with the terms above.
Should you have any inquiries regarding privacy practices while using the Application, or questions about our data handling procedures, please email the Service Provider at bradcliffav@gmail.com.
